PLOW AT-TACH'M ENT.

SPECIFICATION forming part of Letters Patent No. 627,809, dated June 27, 1899.

Application filed August 2, 1898.

' T0 on whom it may concern:

Be it known that 1, WILLIAM NOLEN, a citizen of the United States, residing atMound, in the county of Brown and State of Illinois,

have invented certain new and useful Improvements in Plow Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

The invention relates to an attachment for a plow; and it consists, essentially, of a se-, ries of colters or cutters adj ustably and removably supported on the plow-beam and in positions, respectively, on the moldboard and landside of the -plow and which may be removed in whole or in part or all used, in accordance with the requirements of the work to be performed. I

The invention further consists of certain details of construction or arrangement of the several parts, which will be hereinafter de-. scribed and claimed. The object of the invention is to thoroughly break up the ground as it is plowed and also to provide means for permitting trash or rank growths to pass over the plow without choking the same and also to clear the plow of said trash as it is cut and loosened by the cutters without any tendency to raise the plow from its proper depression, the various parts beferred and suitable construction.

Mounted on the beam 2 at any desired distance in front of the pl'owis a clip 3, carrying a series of cutting-disks. This clip comprises alongitudinal piece 4:,which lies against one side and parallel with the beam 2. Short 7 arms or pieces 5 5 are arranged at right angles SerialN0-687,5 l9. (No model.)

to the piece or arm 4., Secured to the arm 5 is a loop.6, which is secured adj ustably to the said arm and is secured in place by means of nuts 6 6, which engage with the threaded ends of the loop 5. To the arm 5 are secured two cross-arms 7 7, which are also heldin position by nuts7 7. The arms 7 7 on the landside of the plow, beyond the beam 2, are provided with eyes, and in these eyes is supported the shank of the curved or segmental hanger or piece which carries the cutting-disk on the landside of the plow. Projecting at a right angle from the arm 4 or from the beam itself, if desired, is an arm 8, which supports the hangers comprising the shanks and segments which carry the cutting-disks on the moldboard'side of the plow. This arm is held rigidly in position by means of a stay-rod 9, which may be fixed or removable.

of the device, although this stay-rod'9 might be permanent.

The cutting-disks are represented at 10. The hanger for the disk on the landside of the plow comprises a vertical shank or arm 11, supported in the eyes at the endsof the arms 7 7. The lower end of. the arm 11 is somewhat crank-shaped, and its end is screwthreaded, and on this screw-threaded end is secured the curved arm 12,which has a tapped eye for the purpose. The lower part of the arm 12 is bifurcated or slotted, and the cutting-disk 13 is mounted in said slot by means of a short axle which is passed through the segment and the disks. As all the hangers, as far as described, have the same construction, it is unnecessary to describe the disks on the moldboard side of the plow carried by the arm 8. The cutting-disks on themoldboard side of the plow are, however, adjustable both horizontally and vertically. They are adjustable laterallyby moving thehangers toward or from the plow-beam 2, and they are adjustable vertically by recessed blocks 14:, which clamp the hangers to the arm 8 and secure them in position by means of set-screws 15 15. The blocks 14 have recesses 16 on their inner faces, and these recesses are wider than the diameter or width of arm 8 to provide for vertical adjustment.

While I prefer that the arms 12 should be slotted or bifurcated, it is evident that the disks might be secured in any proper manner so that they will be revoluble.

By the construction described the several disks are made to revolve in advance of each other, and thus grass or trash is worked between them with ease, and there is no tendency to throw a light plow out of the ground, as but one of them can strike the same obstructio'n at a time. Furthermore, the construction is such that the disks may be adjusted both laterally or vertically, and any suitable number of disks may be used on the moldboard side of the plow within certain limits. I prefer to use ball or roller bearings at articulated points. The construction also enables the attachment to be readily secured to any plow-beam.

Minor changes in the details of construction within the scope of the invention may be made without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described the invention, what I claim as new is- 1. A plow attachment comprising a nu'n'cv ber of adjustable and removable cuttingdisks or colters arranged in a series laterally and in advance of each other, and mounted to rotate on depending arms or hangers secured to the plow-beam, in combination with asingle plow, substantially as described.

2. A plow attachment comprising a num= ber of cutting-disks or colters arranged in a series laterally and in advance of each other on both the laudside and the moldboard side of the plow, and mounted on depending arms secured to the plow-beam, and means for adjusting the disks, substantially as described.

3. A plow'attachment comprising a number of cutting-disks or colters, mounted to' rotate in dependingv arms, one of said arms being'attached on the landside of the plow and the other arms adjustably and removably attached to an arm at right angles to the plow beam, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM NOLEN.
